Abstract: The iron ore tailings mud and gravel drift mine is the main emission solid waste Bayanobo West Mine Concentrator. Tailings mud instead of sand，drift gravel instead of graded gravel，RCC process was adopted in the mine road construction. It improves the mine haulage road traffic，and extends vehicle service life.The trial achieved its optimum moisture content and the largest proportion of indicators, and 28 d compressive strength of more than 18 MPa industrial test road in the mining area on the main transport ramp, a total of 4, the road length of 66.5 m, width 9.0 m, covering an areaabout 600 m2 with feeding amount a total of 165 t - tailings mud the average strength of roller compacted concrete pavement core samples of concrete strength test results, in more than 18 MPa.

Key words: Tailings mud, Waste rock, RCC, Road dust suppressants
